How a Guy Found 4 New Planets Without a Telescope 133

Posted by Soulskill from the he's-just-this-guy,-you-know? dept.
An anonymous reader writes "Peter Jalowiczor is a gas worker from South Yorkshire, England. He's also the discoverer of four giant exoplanets, according to the University of California's Lick-Carnegie Planet Search Team. But he's not an astronomer and he doesn't even have a telescope. '...in 2005, astronomers at the university released millions of space measurements collected over several decades and asked enthusiasts to make of them what they would. ... From March 2007 Peter, 45, spent entire nights reading the data, working the figures, creating graphs. ... He then sent discrepancies he discovered back to the scientists in California where they were further analyzed to see if the quirks were caused by the existence of an exoplanet.'"

    As an amateur astronomer I think the general mindset is that one cannot make a discovery of any significance without owning cutting edge hardware. Telescopes produce such mind-bending quantities of data that there is much opportunity for someone with some patience and an inquiring mind to add to the knowledge-base.

    Surely also a brilliant argument of the power of publicly available data.

        Well, yes, that's why you don't own it: it's theirs.

        Point is, a lot of the bigger telescopes provide far more data than can be handled by dedicated computing. This has been the case since CCDs were invented decades ago, there's just too much to analyse everything within the budget, so they go for the obvious/important/cheap signals (delete as applicable).

        SETI started distributed computing in a big way, and this is a similar (if far more individually clever) application. It's very muck akin to the way volunteers sometimes sift through spoil on an archaeological dig just in case anything interesting has been missed by the JCBs and WHSs. Good on the guy, it's a fair old achievement and a hobby I aspire to matching.
        • And there are numerous other projects similar to this requiring a human brain rather than distributed computing - or at least where a human brain is still effectively helpful. Galaxy zoo is the past time of thousands and they recently branched out into digitizing old British navy war records for the purpose of long term climate research.

          Generally, you're observing towards an aim. You're mapping transverse velocities in a suite of planetary nebulae, or trying to determine the light curve of an eclipsing binary or whatever your proximal or distal project is. So you analyse the objects that you've targeted in

      Which is completely stupid. How many professional Astronomers own cutting edge hardware? None, that's how many. The hardware is so expensive that it is owned by Universities, governments, research institutes, etc. and there's only a handful of people on the planet with enough money to buy one and fund its operation. It's not like the observations were made using a $50 telescope from the Kid's section at Wal-Mart.

There really isn't any difference between looking at the output screen at the observatory and looking at a spreadsheet of that same data, you're still using the telescope.

        The big difference is that, since telescopes can record that mass of data, now we can all use the telescope at once, all looking for something different. That's pretty cool.

For less than £10000 it's possible to get hardware capable of photographing impact events on Jupiter in reasonable detail. If you pick up pre-owned gear you can get it significantly ch

Even so, they can't look at every star, and so there's always some data that goes un-analyzed.

      Um no. Typically the guys up in the middle of the night taking a series of long exposures are NOT the multiple PHD astronomers. It's college kids working on their Masters or Phd. Running a telescope is actually quite easy, you do what the Researcher asks, and then deliver the data. It's been this way for a while now. you dont have the old guy spending all night looking through an eyepiece with the guide motor controller in hand. In fact a friend of mine that works at UofM astronomy was making observations during the daytime by using a scope in Australia and had the data and images sent to him, he then did the processing.
